An educational BaZi case study of Barack Obama's chart, presented as a learning example without absolute prediction claims. His birth time is on official record (1961-08-04, 19:24 Honolulu — Rodden AA), so this is a complete four-pillar reading — Year 辛丑, Month 乙未, Day 己巳, Hour 甲戌, Day Master 己 (yin Earth), born in the Earth-heavy 未 month.
The defining structure: a heavy Earth self channeled out through expression and reined in by public authority. The Output stars (食伤, Metal) are the Favorable Element — turning a deep inner world into persuasive language — while Direct Officer at the hour and Seven Killings at the month mark a structure naturally aligned with public office. The chart's main caution is "Peers & Rivals" (比劫): an outward dynamic of allies and contenders, not inward self-conflict.
